High-Tech Case Study: Tools For Learning
A Chat With Robert Cole
Project Superintendent Loma Linda UniversityWhat are your responsibilities at Loma Linda University? I am one of five project superintendents at the university. During construction projects, I act as the owner’s representative. For the Centennial Complex, I oversaw McCarthy [the general contractor] and also interacted with all the subcontractors. The budget was also under my watch. Once assigned to a project, I run it from cradle to grave. How long have you worked at Loma Linda University? I have worked here for 23 years, with the last 12 years as a project superintendent.
Construction TechniquesDue to the abundance of underground electronic lines and tie-ins for computer workstations in the Centennial Complex, the McCarthy Building Companies team, the general contractor, suggested pouring a sub-slab on the grade portion of theater seating areas. This provided the ability to map underground feeds in the sub-slab and enabled greater forming accuracy, which saved time and money. Robert Ragland, project director for McCarthy, explains, “The sub-slab became a working surface, and we could create a more detailed layout of the lines that would be put in. This provided the electricians and the plumbers with a working surface; they could measure more accurately working on a hard surface versus soil.” Time saving strategies were also employed in the construction of the utility tunnel. The tunnel connects to LLU’s central plant and handles chilled water, electricity, and communications infrastructure as well as transporting water for medical instruction. The water used in medical instruction must be handled in a specific manner, and the tunnel project required approvals from the California Office of Statewide Health Planning and Development (OSHPD).
OSHPD approval can be a time consuming process, and one focus was to minimize delays in setting up utilities while waiting for approvals. The project team evaluated several options and ultimately decided to install temporary power and water lines from the central plant and existing campus power infrastructure to the new construction. (McCarthy’s Ragland notes, however, that temporary chilled water was not needed at the time due to the seasonal climate.)
“Putting temporary utilities in place allowed for testing, inspections, and balancing the building’s mechanical and electrical systems while waiting for OSHPD approvals,” says Ragland. “When the approvals came in and the tunnel was completed, we were able to switch quickly over to the permanent utilities and do final commissioning. So when students and staff occupied the building in Fall 2009, everything was in permanent condition. The temporary utility strategy allowed the building to be ready on time.”
Maintaining MomentumCole’s ongoing involvement ensures he is aware of any facility problems that may arise, though he notes they’ve been minimal. “Fortunately, the contractors were very proactive in addressing any issues,” he says. “Considering the size of this project and the complexity of the commissioning process, we’ve had very little problem with operations.” This article was based on interviews conducted with Breyer, Cole (www.llu.edu), and Ragland (www.mccarthy.com).
